AUTOMATIC TELEGRAPH-REPEATER.

SPECIFICATION formingpart of Letters Patent No. 558,042, dated April 14, 1896.

. Application filed December 26, 1893 Serial No. 494,734. (No model.)

To all whom it may concern:

Be it known that I, ALBERT EDWARD CoLL- YER, a citizen of the United States, and a resident of Monmouth, Warren county, State of Illinois, have invented certain new and useful Improvements in Automatic Telegraph'Repeaters; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention relates to telegraphy, and more especially to instruments used in that art and which are known as repeaters; and the object of the same is to produce an instrument of this character which will repeat without the use of a local battery and will steady the current, and one that can be used at the point of crossing of two lines.say north-south and east-west--so as to permit an operator on I either line to communicate with another op erator either on the same line or on the other line.

To this end the invention consists, essentially, of two common relays or electromagnets whose armature-levers carry inwardlyprojecting lugs, a single rocking bar mounted between said levers and having an inclined and a flattened portion at each end adapted to be engaged by one of said lugs, springs holding said bar in a normally-horizontal position and at that time making contact with posts, and means for permitting the bar to be turned on a vertical pivot, so as to throw its ends out of line with and hence out of control of said lugs,but yet not to throw its springs out of contact with their posts, the whole be-.

ing designed for use as and of the specific construction set forth in the following specification and illustrated in the drawings, wherein- Figure 1 is a side elevation of this repeater, partly in section, and also a diagram showing the circuits and connections. view of the repeater with its bar turned slightly, so as to be out of engagement with and control of the lugs on the armature-levers.

Referring to the said drawings, the letter R'designates my improved repeater, from the center of whose base rises a tubular socket 1,

1 having in one side a laterally-enlongatod slot Fig. 2 is a plan 2, and 3 is a cylindrical stem which fits loosely in said socket, while a set-screw 4 passes through said slot and screws into the stem. The head of said stem is forked, as at 5, and the arms of the fork carry the usual screwbearings 6,proj ecting inward an d held in place by jam-nuts 7 v 8 is a horizontal bar of insulating material, having across its center a journal 9, with pointed ends engaging said bearings 6, so that the bar can rock thereon. At the ends of the bar depend hooks 10, which support the outer ends of springs E N whose inner ends are secured by screws 11 to the lower side of the bar near its center, and set-screws 12 with jam-nuts 13 pass downward through the bar for adjusting the springs, as will be clear. Rising from the base at proper points are posts E N which normally make contact with the outer end of said springs just inside of the hooks 10, as seen.

a n are two electromagnets supported in any suitable manner at the opposite ends of the base, and as they are of similar construction a description of one will answer for both. The armature 20 of the magnet c has an upright armature-lever a, suitably pivoted at 21 to the base and drawn normally away from the magnet by a spring 22, whose tension is adjusted by a screw 23 in the usual manner. When the magnet is energized, the upper end of the lever 01 makes contact through its point 24 with a point e, but when the magnet is deenergized the lever falls back against an insulated stop or screw 25.

On the outer side of the lever is a lug 26, so located that when the lever falls back the outer end of the lug strikes and rides up an incline 27 on the adjacent end of the bar 8, thereby depressing this end of the bar against the tension of spring N and raising the opposite end of the bar, so that spring E is lifted by its hook 10 off the post E and the flat portion 28 at the highest end of the bar is raised to a point opposite the lug 26 on the other armature-lever if, as seen in dotted lines in Fig. 1. Thereafter, if the magnet e is deenergized and its armature-lever n falls away, it is obvious that it can fall only a slight distance, because its lug 26 will strike the flat portion 28 on the then raised end of the bar 8. On

renergizing the magnet a its lever a will be again attracted and the lug will move off the inclined portion 27 at the then lower end of the bar 8, so that the spring N will throw the lever again into a horizontal position with both lugs free and both springs resting on their posts.

If the screw 4 be loosened, it will be obvious that the entire bar 8, with its springs E and N can be turned on a vertical pivot, so that the cylindrical stem 3 turns slightly in the socket 1, the screw moving in the slot 2, and after adjustment the screw is again tightened; but it is to be understood that said springs E and N are broad enough so that during such turning they do not pass off the points of the posts E and N.

Fig. 2 is a plan View of this repeater complete,-and it illustrates the bar 8 as having been so turned. turning of the bar throws its ends out of ver: tical alinement with the armature-levers, and therefore if those levers are afterward moved by denergizing their magnets it will be clear'that their lugs 26 will not engage the inclined or flat portions at the ends of the bar 8. manner throws it entirely beyond a point where it would be rocked or controlled in any manner by the magnets, and if it cannot be rocked it is obvious that the springs make constant electrical contact with their respective posts. At any time desired the screw 4 can be loosened and the bar turned back to its original position. The purpose of this turning will appear below.

The running of currents as employed in connection with the above-described repeater is as follows:

46 N, (4 S, ('E) 77 designate, respectively, the operators to the north, south, east, and west, from which points the wires lead to my repeater, which we will suppose is at the crossing of the northsouth wire with the east-west wire.

SN is the switchboard on the north-south wire, and SE is that on the east-west wire. The wire'from the south leads from'its switchboard SN at the'point n, thence, as at n, to

a binding-post in the base of the repeater,

thence, as at 01 to the point 92 thence down the lever n and through the pivot 21, thence by wire a to a point a on the switchboard, and thence by wire of through the coils of the magnet n and on to the north. From the switchboard SN a branch circuit leads from the point N by wire N to a binding-post in the base of the repeater, thence by wire N to the spring N to post N and thence by wire N to a point N on the switchboard,

which is plugged to connect with the point a, and thence by Wire 42 through the coils n andon to the north.

Thus it will be seen that the north-south current has two paths through this repeater one from the switchboard, by the wires 17. and

71 through the armature-lever of the magnet It will be noticed that the:

Hence the turning of the bar in this at the then higher end of the bar.

6 and the other, by wires N N, through the spring N of the rocking bar 8. The eastwest wire is exactly a counterpart of the northso uththat is to say, coming in from the west it leads through (2, wires e and 6 point 6 lever a, wire e plug 6 wire 6 and magnetcoils c onto the east, and the branch leads from the switchboard SE through plug E, wires E and E spring E post E, wire E plug E, plug 6 wire 6 and magnet 6 onto the east.

Supposing now that north desires to coinmunicate with some person on the east-west line. 111 the first place south may be cut out, if desired, and north connected with ground, which is done by suitable plugging, as will be understood. The switchboards are also suitably plugged to make the connections described below and the operation is as follows: North opens his key, thus breaking the circuit on line n and allowing'the lever e to fall back under-the pressure of its spring 22. In so falling back the lug 26 strikes the inclined portion 27 at the right end of the bar 8, and the latter is rocked to the position indicated in dotted lines. WVhen the lever falls back, the circuit 6 e is broken between the points 24 and e" and hence the east-west circuit is complete only through the branch E E but as the bar 8 moves to the dotted position shown spring E rises from contact with post E and hence this branch of the east-west line is broken. Therefore when north opens his key the east-west line is broken. Such breaking of the east-west line denergizes magnet e and its lever n is drawn by its spring 22 away from point of, but as the bar 8 stands in dotted position it is obvious that the lug 26 will strike the flattened portion 28 The movein ent of this bar away from the point n breaks the circuit n a but the north-south line still has another complete path'from the switchboard SN through the circuit N N 5 and spring N which latter, though raised from its hook 10, rests on its post N North now closes his key and the current flows in through magnet n wire of, branch N N and onto the south, or to the ground if south be cut out. The

magnet a then attracts its armature, which moves lever e to the full-lined position of Fig. 1, thereby closing the circuit a 6 through thepoints 24 and c and hence closing all the instruments in the east-west line. As the lever 6 thus rises, its lug 26 releases the right end of the bar 8, and the latter resumes its horizontal position, so that spring E makes contact with post E and the branch circuit E E in the east-west line is also closed. The current now flowing through the wire 6 causes magnet e to draw the lever n away from the left end of the rocking-bar 8. Thus it will be seen that north can communicate with cast and west, or with either east or west if the other be cut out, and south may be meanwhile cut out or not, as desired, and obviously the same would be true of any other point or points of compass which are connected with this instrument. In this manner my invention can be used to telegraph from one point to any other.

Supposing now that north and south wish to communicate with each other, but desire to cut out east and west, set-screw 4 is loosened and the stem 3 is turned in the socket 1, so that the bar 8 assumes the position shown in Fig. 2, and thereafter any current on line n which causes magnet 01 to move its lever 6 will open and close the circuit e a but the lug 26 will not engage the inclined portion 27 of the bar 8, and hence the latter will not be rocked, and its springs E N 3 will make constant contact with their respective posts. The bar 8 being thus turned, line n is still complete to the south through plugs N N, branch N N, spring N and post N and hence north and south could telegraph to each other. As the current in the line a would open and close the circuit 6 6 which is in the east-west line e the plugs e e are removed, so that east and west are partially cut out, although they still have a complete circuit through the branch E E and spring E. In the same manner east and west can communicate with each other and north and south can be cut out. In this manner my invention can be entirely out out by simply turning the bar 8.

Supposing now (under the above conditions) that a local instrument is desired in the north-south line, plugs are inserted in the switchboard SE at the points L L whereby the circuit e e is connected with a local circuit Z, which leads through a local battery and instrument LN, and thereafter magnet 02. and circuit e a will act as a repeater and will duplicate on the local instrument the messages between north and south. In the same manner the messages between east and WVGSU could be duplicated by suitably plugging the switchboard SN to another local circuit Z and its instrument.

which will be understood.) In this manner my invention can be used in the place of two net a (which is operated by the current in line 11 becomes a relay, and hence by suitable plugging (not shown, but which will be clearly understood) south can be connected I with wire 6 and wire 6 can be led throrwh a relay-battery to the ground. Thereafter each impulse on the line from the north will energize magnet a and will close a circuit from the ground through this relay-battery,

(Not shown, but

through circuit 6 c and on to the south. In the same way a relay can be inserted in the east-west line; a In this manner my invention may also be used in the place of two relays.
